ASTM A790 S32205 Duplex yeeb nkab hlau yeeb yaj kiab rau corrosive ib puag ncig
ASTM A790 S32205 Duplex cov yeeb nkab stainless hlau yog qhov siab {{} {} {} {} {}. Nws ua kom pom zoo ua kom tsis kam ua rau chloride kev ntxhov siab, pitting, thiab cov roj av zoo nkauj rau cov ntaub ntawv xws li roj thiab siv tshuaj lom neeg, thiab sab nrauv engineering. Cov yam ntxwv tseem ceeb suav nrog cov txiaj ntsig zoo ntawm 65 ksi, ib qho tsawg kawg tensile lub zog ntawm 95 ksi, thiab cov kws kho mob zoo, suav nrog kev qaug zog nkees.
Dab tsi yog cov tshuaj lom neeg muaj pes tsawg leeg ntawm ASTM A790 unu s32750?
ASTM A790 UNSIVE S32750 (Duplex 2507) Yog super duplex stainless hlau muaj 25% chromium, 4% molybdenum, thiab 7% npib tsib xee. Nws yog siv rau seamless thiab welded ferritic / austenitic stainless hlau yeeb nkab.

Corrosion Kuj
Chloride kev ntxhov siab corrosion (SCC): S32205 yog qhov tsis tshua muaj chloride (s32205 yog qhov tsis muaj peev xwm ntawm cov qauv Austenitic hlau xws li 316L.
PITTING THIAB CREVICE COLAMION: Nws cov chromium, molybdenum, thiab nitrogen cov ntsiab lus muab rau cov corrosion corrosion.
Acidic thiab ntsev ib puag ncig: nws ua tau zoo nyob rau hauv ntau cov kev tawm suab, suav nrog acidicive thiab chloride {{main} nplua nuj ib puag ncig xws li Sealwater.
Cov Khoom Siv Neeg Kho Tshuab
Lub zog siab: nws lub siab xa lub zog thiab lub zog tensile pab txhawb rau nws txoj kev kav ntev.
Kev qaug zog: Cov khoom ua pov thawj zoo nkees lub zog, ua rau nws haum rau Cyclic Loading daim ntaub ntawv.
Kev Txiaj Ntsig: Kev Tshawb Fawb Tseem Ceeb Tshaj 25% Qhia Txog Kev Tsim Kho Zoo.
Muaj pes tsawg
Cov Ntsiab Lus Tseem Ceeb: Cov hlau no muaj cov roj ntsha muaj cov chromium siab (22-23%), molybdenum (3.00-3.20-0.20%).
Microstructure: Cov hlau no muaj lub duplex (ferrite - paustenite kwv yees li 50/50 ntawm ib feem ntawm austes thiab ferrite theem.
Zoo thiab Testing
ASTM A790 Txuj Ci: Yeeb Nkab yog tsim raws li Astm A790 cov lus qhia tshwj xeeb.
Kev kuaj: S32205 yeeb nkab undergoes undergoes foregoes foregoes ntau qhov kev kuaj ua ntej cov zaub mov xa tuaj, suav nrog hydrostatic, tensile, thiab ua tsis tau zoo.
GNee steel tshwj xeeb hauv kev tsim cov nickel - raws li alloys. Gnee Steel cov khoom ntim khoom lag luam muaj cov khoom lag luam hlau: cov kav dej nrog cov kab yeeb yaj kiab uas tsis muaj xeb, thiab tsawg dua yog kev nyab xeeb nrog cov steel strapping. Cov thawv ntoo / crates: kav ib txwm ntim hauv cov thawv ntoo lossis crates los tiv thaiv lawv thaum lub sijhawm tsheb thauj mus los, tshwj xeeb yog diameters. Seaworthy export ntim: Cov chaw muag khoom siv cov txheej txheem seaworthy export export cov ntaub ntawv sau thiab cov tswv yim los tiv thaiv cov kav dej thaum lub sijhawm thauj mus los. Tarpaulin Ntim: Qhov no tiv thaiv nag, hiav txwv dej hiav txwv, thiab lwm yam sab nraud sab nraud los ntawm kev nkag ntawm cov chaw ntoo sib tsoo thaum lub tsheb thauj khoom thaum export thaum thauj khoom. GNEE steel tshwj xeeb hauv kev tsim khoom thiab muag khoom ntawm alloy cov ntaub ntawv. Gnee Steel cov khoom yog dav siv nyob rau hauv Aerospace, tshuaj lom neeg, siv hluav taws xob, thiab peb tuaj yeem muab zog alloymy cov kev daws teeb meem raws li cov neeg siv khoom xav tau. Rau aluminium cov khoom siv nqe lus los yog customized alloy cov kev daws teeb meem, thov hu rau peb rau ib nqe lus ntawmss@gneesteel.com.
